Oslo – October 15, 2026 -- TGS has secured multi-client rights from state agency PetroGuin to reprocess more than 11,000 km2 of JAAN 3D seismic data across Guinea-Bissau, with final products due in Q4 2027.
TGS builds on 2019 reprocessing with new imaging tools
The agreement builds on the parties' previous 2019 PSDM reprocessing. TGS will apply elastic dynamic-matching full waveform inversion (E-DMFWI) and Kirchhoff pre-stack depth migration (KPSDM). The company expects a significant uplift in image quality compared with the existing data.
Improved imaging targets clastic and carbonate plays
The upgraded images are meant to improve assessment of both clastic and carbonate targets across the margin. TGS says this will give explorers greater confidence in evaluating prospectivity as they plan future exploration activity in Guinea-Bissau.
